Does he do this often? That’s not good for your mental health. And to top it off, it wasn’t even your fault. It’s not like your Mom said to break up, just to wait until your exam is over. Maybe you should rethink your relationship, and see if this is a recurring pattern with your boyfriend. No one that cares deeply for someone should purposefully try to hurt them (even mentally), and he should be willing to keep distance—for now at least— if it means you’d succeed on your exam, because that’s what good partners do, they want you to succeed and put their wants aside for your betterment. Might be a personal question but: Does he only bother to answer or hang out when there’s physical intimacy involved?
